### Property Value
A [Bitmap](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Bitmap.htm.md) class instance which represents a red eye mask.
 
## Remarks
  
A pixel format of this bitmap is always [Format8bppGrayScale](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_PixelFormat.htm.md). White areas corresponds to portions of the source image which are recognized as red eyes (i.e. *red eye blobs*). If you need to get coordinates of the red eye blobs, use the [Blobs](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Transforms_RedEyeMask_Blobs.htm.md) property. It will return an array of [RedEyeBlob](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_Transforms_RedEyeBlob.htm.md) object.
